Pre Arch Control Technology of Double Layer Bailey Beam Support Method for Cast-in-place Simply Supported Box Girder
With the widespread application of the Bailey beam support method in the construction of cast-in-place box girders,especially in the design of double layered Bailey beams with single span when crossing existing highways and rivers,it is particularly important to control the pre arch degree based on the pre compression test.In this article,combined with the pre compression test of the double layered Bai-ley beam support method for the Yingpanshan Bridge on the Menghua Railway,we will elaborate on the process,purpose,and significance of the pre compression test.By organizing and analyzing the preloading data,the required pre arch degree for the template was determined,providing a basis for guiding the con-struction of box girder concrete pouring.It is hoped that this can provide some reference experience for similar bracket construction in the future.
